剩余油饱和度测井是指在高发水期开发油田时寻找剩余油的一个重要的方法,在当前的科技状况下,能够利用套管测量剩余油饱和度的方法有过套管电阻率测井,中子寿命测井和碳氧比测比等,根据储层饱和度测井仪对测井特点的研究,合理的解决了地层水电阻率和泥质的涉及问题,利用了各种不同的方法来进行对剩余油饱和度的测井分析。套管井剩余油饱和度测井技术是在开发油田里必不可少的一种测井技术,油田不断的被开发,不论是对地下进行二次采油还是三次采油都需要对地下的油层情况有详细的了解,包括油层水淹的程度和油藏内水和气的分布状况,为了提高储层的采集率,就需要利用剩余油饱和度的参数为依据。
Remaining oil saturation logging is an important way to look for residual oil when developing oilfields in high water regimes. In the current state of science and technology, the method of measuring remaining oil saturation with casing has been done by casing resistivity logging , Neutron lifetime and carbon to oxygen ratios, etc. Based on the study of well logging characteristics of reservoir saturation logging tool, the issues concerning formation resistivity and mud quality are reasonably solved, and various kinds of Method for logging analysis of remaining oil saturation. Cesium wells remaining oil saturation logging technology is an indispensable in the development of oilfield logging technology, oil fields continue to be developed, whether underground or tertiary oil recovery needs detailed information on the underground reservoir conditions Including the degree of water flooding and the distribution of water and gas in the reservoir. In order to improve the reservoir acquisition rate, it is necessary to use the parameters of the residual oil saturation as the basis.
